(c1. sis-+1) My. invention. relates to. improvements :in r r My manner; offolding is'as follows method of making radiator shields by, folding, and I has for its primary object the method of folding v a sheet of paper intoform so astolact as a radiator shield, the foldingbeing accomplishedona fiat surface and withoutthe aidof any special form;

A-- further object is togfold a paper. radiator shield in sucha manner .that'it canbe readily stacked for storage-and when so folded will occupy a very small space. g i

In carrying out my method, I provide a sheet of paper I 3 having ends l4 and I5. These ends are parallel to each other. The sheet 13 also has edges l6 and ll which are parallel to each other and extend at right angles to the end: M for a-predetermined' distance terminating at a pointindicated by the numeral l8. g

' From the point,l.8-, I provide inclined edges 19' which terminate at the end l5. In folding my device, creases or score marks 20-2 l22 23 and 24 are formed which are parallel to the ends I4 and I5. Creases or score marks 25 and 26 are formed which extend at right angles to the creases 2fl--2l--2223 and 24 and are positioned at a predetermined distance from the edges l 6 and [1.

It will be noted that these creases are parallel to each other and to the edges 16 and I1. Continuing the folding area plurality of creases 21- 28 28-30-3 l--32- 3334-3 536-31--38-- 39-40-4I-42-43 and 44; The last mentioned creases are formed diagonally to the previously mentioned creases or score marks, r a

This completes the fold A sheet is laid out flat on a table' or other plane surface and then folded along the line I 24]; thus bringing the lowerportion ,ZAA of 'the shield or sheet-upward'as illustrated '-i r "Fig. 2. The next step jis to apply paste "'as' indica'ted-by the numeral 45 to the portion MA and 'thentur-n that. portion 14A down along the line- 20'a's illustrated 1 in Fig. 2., The next step; is to fold the sheet diby thenumerallt and the paste-covered:corners 1 then folded over on-themselves; as'infiFigi 6 after b which the'portion 49 'is -turned uridrs'othlt; the j shield willthen have'xthe appearanoaas showii in Fig. 7. The sheet -is' then foldedover'along the lines 29 and 30 as indicated inFig-.' and then paste is applied to the portions 41 and 48 5 after which the projecting portion 5!) is folded over on the pasted surfaces 411and 48 as in Fig; 9. The projecting portion at the bottom of the sheet when so folded will be triangular as illustrated flap 5!. The device will now have the 'appear- ,ance' of Fig. 10, after which the two upper corners t 52 of the sheet are then folded over'portions 50 ing leaving the sheet in such a shape that it resembles an envelope. I 1

It will be noted from Fig. 12 that the devicelies perfectly flat .and occupies very little'space,

consequently they can be readily stored" and 40 packed-for shipment and by reason of employing the paste when the shield is unfolded; it

will assume the proper shape automatically and no extra folding .or shaping of the parts is re quired, thus it will be-seen that I form a shield of flexible material for radiators which extends down the back of the radiator, partially along" the sides. oven-the entire. top anddown over a 1 small portion .of the front and due to myfpar-' ticular folding, the portion between the end I4 and crease line 26 extends upward at an angle and forms a dust trap so that dust which is drawn up by the heat of. the'radiator will strike the top and instead of being forcedvinto the patent application, Serial .No. 344,239 filedf'rby;

may be readilyremov'ed.

'such a nature that it willno-t have its adhesive;
